An apparatus is provided that includes a microcontroller to facilitate data communication within a system comprising a plurality of peripheral devices, a power manager to put the microcontroller into a sleep state to save power, and an I/O controller to enable communication between two or more particular peripheral devices in the plurality of peripheral devices without involvement of the microcontroller while the microcontroller is in the sleep state. The microcontroller is to wake from the sleep state in response to at least one signal from a component of the system external to the microcontroller and communication between at least some of the plurality of peripheral devices is facilitated using the microcontroller when in an awake state.

Non main CPU/OS based operational environment

Some embodiments describe techniques that relate to hybrid graphics display power management. In one embodiment, data corresponding to one or more image frames of a video stream are stored in a local frame buffer. A display device (e.g., an LCD) may then be driven based on the stored data in the local frame buffer or a video stream from a graphics controller. Other embodiments are also described.

Hybrid graphics display power management

An embodiment of the present invention is a technique to dynamically swap processor cores. A first core has a first instruction set. The first core executes a program at a first performance level. The first core stops executing the program when a triggering event occurs. A second core has a second instruction set compatible with the first instruction set and has a second performance level different than the first performance level. The second core is in a power down state when the first core is executing the program. A circuit powers up the second core after the first core stops executing the program such that the second core continues executing the program at the second performance level.

Dynamic core swapping

A computing system is described that includes a main system bus that remains active while said computing system operates within a non main CPU/OS based operational state. The computing system also includes a controller that operates functional tasks while the computing system is within the non main CPU/OS based operational state. The computing system also includes an I/O unit coupled to the main system bus that remains active while the computing system operates within the non main CPU/OS based operational state.

Various methods, apparatuses, and systems are described in which a chipset controller has circuitry to control communications with a peripheral device in a computing device. The chipset controller has logic configured 1) to detect a plug-in event when the peripheral device connects to the chipset controller and 2) to transition the chipset controller from a low power consumption state to a higher power consumption state based on the logic detecting the plug-in event.

Various methods and apparatuses for power states in a controller

Various embodiments are generally directed recurringly cycling the driving of a platter media of a hard drive with a motor, allowing rotation of the platter media to slow only to a threshold rotational speed to balance power conservation with delays in accessing data. A method comprises driving platter media of a hard drive to rotate at a selected normal rotational speed, retrieving data stored on the platter media when the platter media rotates at the normal rotational speed, ceasing to drive the platter media to rotate to allow the platter media to rotate under rotational inertia imparted to the platter media, monitoring a current rotational speed of the platter media, and resuming driving the platter media to rotate based on the current rotational speed falling to a lower threshold rotational speed selected to be less than the normal rotational speed. Other embodiments are described and claimed.

Power conservation based on hard disk rotational inertia

A low power subsystem for a portable computer is described. In one example, the portable computer includes a computer system and low power multimedia center. The computer system includes a central processing unit, a system memory, a mass storage device, and a user interface, the computer system having a low-power mode in which the CPU, system memory, and user interface are inactive. The low-power multimedia center includes a low power processor coupled to the mass storage device, a low power memory coupled to the low power processor, a miniature display to display multimedia from the mass storage device, and an external user interface coupled to the processor, independent of the computer system to control the displaying of multimedia.

Low-power subsystem for portable computers

A wireless device is disclosed. The wireless device includes a wireless communication module, a data storage module, and a controller for controlling the storage and/or retrieval of data from the data storage module. The wireless communication module communicates with each of a plurality of remote devices and the data storage module defines a first storage area and a second storage area. The controller controls the communication of data between the first storage area and the remote device, and the second storage area and the remote device dependent upon access rights associated with the remote device. The first storage area typically defines a public storage area with which data is exchanged in a relatively free manner, and the second storage area typically defines a private storage area with which data is exchanged in a relatively restricted manner.
